Heal your own teeth: Remineralization of tooth enamel

    [1]remineralization-an   Remineralization is the process of
  restoring mineral ions to the tooth structure, and can be
  compared to replacing the missing links in a chain. The lost
  mineral ions must be replaced with ions of the same shape, size
  and electrical charge. Remineralization involves carbon dioxide
  from breath and water from saliva to create a mild, unstable
  carbonic acid that is at the core of the natural
  remineralization process. Minerals in saliva present from food
  are dissolved by the carbonic acids. In addition, carbonic acid
  quickly and easily converts to carbon dioxide and water. When
  this happens, the dissolved mineral ions precipitate out as
  solid mineral ions again, but not always as the original mineral
  molecules. If a particular mineral ion is near a demineralized
  portion of the hydroxyapatite crystal that requires that ion,
  the ion is incorporated into the dental enamel. Though natural
  remineralization is always taking place, the level of activity
  varies according to conditions in the mouth. In fact, for
  remineralization to proceed, six conditions or events must occur
  at the same time: * Sufficient minerals must be present in the
  saliva. Food is the principal source of minerals for the teeth,
  therefore an adequate diet and sufficient time spent chewing
  (this transfers minerals to the saliva) is vital. * A molecule
  of carbonic acid must be produced. A very small fraction of the
  carbon dioxide from the breath is converted to carbonic acid. *
  The carbonic acid molecule must be produced in proximity to a
  mineral molecule, which then dissolves into its ionic
  components. * This all has to occur in proximity to a
  demineralized spot in the hydroxyapatite latticework that
  requires the exact mineral ion. * The demineralized spot has to
  be clean and accessible so the mineral ion is attracted to the
  *hole* in the lattice by the opposite electric charges of the
  ion and the *hole.* Many different ions have the correct charge,
  but only the correct ion has the correct shape and size to fit
  into the *hole.* * The carbonic acid must convert to carbon
  dioxide and water before any of the above circumstances change.
  When this happens, a mineral ion is precipitated out of solution
  into the structure of the enamel.1,2 Since natural
  remineralization is frequently inadequate to maintain strong
  enamel, especially in today*s world of processed foods and
  refined sugars, the natural remineralization process needs to be
  augmented. Remineralization must be enhanced, or
  demineralization must be retarded.1,2

  There are currently three technologies that offer claims of
  remineralization: * Recaldent, found in GC America*s PROSPEC MI
  paste and Trident chewing gum * Amorphous calcium phosphate
  (ACP) found in Arm & Hammer*s Enamel Care Toothpaste, Discus
  Dental*s Nite White bleaching gel and Premier Dental*s Enamel
  Pro polishing paste * SensiStat, found in Ortek Therapeutic*s
  Proclude and Denclude products1,2,3 See the related boxes in
  this article for more information. Also worth mentioning is a
  new technology called NovaMin, a synthetic mineral composed of
  calcium, sodium, phosphorus and silica, the driving mechanism
  that binds to the tooth surface. The sodium buffers the pH to
  allow for precipitation of crystals onto the tooth surface.
  There is a rapid and continuous release and deposition of a
  natural crystalline hydroxyl-carbonate apatite (HCA) layer that
  is chemically and structurally the same as tooth mineral.
  SootheRx by OMMII and Sunstar Butler*s NuCare prophy paste both
  contain NovaMin.7 Patient care strategies One of my colleagues
  who works with the JP Institute told me that as a trial, she
  placed two of her patients on SootheRx. Both of these patients
  suffered from such severe sensitivity that they could not
  tolerate a continuing care visit. The protocol for SoothRx is
  use twice a day for two weeks followed by once a week for six
  months. After only two weeks, the patients returned for
  continuing care with complete relief. By using SootheRx once a
  week, the patients continue to be sensitivity free. There are
  several ways to treat a caries infection, most of which involve
  combined home use of chlorhexidine and fluoride. With
  remineralization therapy, areas in the patient*s mouth that are
  demineralized and run the risk of cavitating have a good chance
  of remineralizing before cavitation occurs. Of course, anything
  that can be done to assist the patient in reversing the
  demineralization process is of significant value. Since
  demineralization occurs when the tooth undergoes an acid
  challenge, the first step is to reduce the frequency of that
  challenge. Nutrition and diet are a chief concern, especially
  today where we encounter more processed than fresh food. Telling
  patients of the importance of fresh fruits and vegetables, which
  provide the minerals our bodies need to naturally remineralize
  the tooth structure, should be part of the recall or continuing
  care hygiene protocol. For those who have active decay or areas
  of demineralization (white spots), daily use of a chewing gum
  with ACP is highly recommended, in addition to a healthy diet.
  Trident Advantage, Trident for Kids, and Trident Whitening all
  contain appropriate amounts of ACP. Two sticks of gum should be
  chewed for five minutes, five times per day to assist in the
  remineralization process and maintenance of healthy saliva
  flow.6 My current patient recommendation is to chew the ACP gum
  for five minutes after breakfast, after lunch, mid-day, after
  dinner and before bed. This accomplishes the suggested *five for
  five* per day regimen to remineralize the affected areas.
  Patients may use MI paste at home. They simply brush, floss,
  then rub the MI paste on the demineralized areas with their
  fingers. No rinsing is needed. MI paste is also well utilized
  during a hygiene visit when applied with the rubber cup in the
  same way as polishing, without rinsing afterward.3,4 For ongoing
  home use, the clinician should recommend Enamel Care Toothpaste
  with ACP by Arm & Hammer. Replacing daily use of regular
  toothpaste with ACP makes the calcium and phosphate readily
  available for use in the saliva. Keep in mind the need for
  fluoride use if toothpaste with fluoride is omitted.8 For
  in-office use, a polishing paste containing one of the
  remineralization technologies should be used with each
  periodontal maintenance or continuing care appointment. Either
  Enamel Pro or Proclude will meet the in-office requirements. The
  greater our ability to arrest disease and the more we take
  advantage of remineralization technologies, the better our
  patients are served. Clinicians should research these products
  and their application for home use by the patient, as well as
  professional use. Your patients will be glad you did. ==== from
  ken === I've been chewing on magnesium hydroxide tablets (mint
  flavored antacids, Walgreens brand) right after I eat, and I've
  been noticing, just in the past WEEK, the dental caries I have
  near the gumlime are starting to fill in!!! I'm shocked and
  amazed. Also, my tooth pain has gone. So: Neutralize the acid in
  your mouth as SOON as it gets in there (eating, drinking, etc)
  and you'll see a difference. Your gums will be tighter too!! ===
    Calcium Zinc as a possibility of toothpaste?
